re: Emile, WL. He gets funding as an elite South African athlete and is on the same time zones as Europe , one 10-12 hour plane trip away from their meets.
I don't think I'd consider Australia, except as a visiting athlete to compete in some bigger meets and enjoy a holiday for a few months.
My South African son-in-law has lived here for 6 years, no criminal record, worked the whole time here and pays tax, married to my daughter and they've had 2 children - still he is jumping through hoops to get citizenship. Last I heard he was awaiting his "invitation" to become a citizen.
